The SSD1730 is a power chip for operating four-line MLA (Multi Line Addressing) LCD drivers. It consists of a
CMOS charge pump-type voltage converter that can generate all the bias voltages required for the four-line MLA
drive based on a single power supply input.
This can be used for the system that is formed by a column (segment) driver such as SSD1870 and a row
(common) driver such as SSD1881. Such type of display system is able to produce a module with lower power
consumption when comparing with the conventional driving method.
voltage-side power supply voltage terminal –V1
